Hey, you both were right! React Native started getting installed inside packages/mobile/node_modules, which is wrong. Changing the path is not the right solution though.
I investigated and you need to make sure all your dependencies have the exact same version between the monorepo packages. For example, change your "react" dependency inside the mobile and web's package.json to the exact same version (e.g. 16.8.4).
This will make react-native get installed in the root node_modules again and also prevent multiple instances of react being installed in the same project, which would cause all kinds of bugs.
Updated the tutorial and also the repository: github.com/brunolemos/react-native...
